Gpz1000rx mis-fire Hi. I have a 1987 GPZ1000RX which has developed a mis-fire and started spitting fuel out of one of the carbs . It seems ok at higher revs but low down it is terrible. I have tried new plugs but it is still the same. Any ideas folks ?? Thanks

This might sound too obvious, and you've probably already tried it, but have you stripped and cleaned the carbs yet? could be worth a go, or you could try draining and balancing them first.

Triumph Legend 1998 same as Thunderbird 900motorcycle running badly.

Was the bike working okay after the overhaul? Mis firing due to bad setup or very bad fuel.If it has not run right since the work was carried out ask the repairer to take a look.
If it only started to go awry after using wheap fuel, (it should still be of uniform quality with other fuel,)
I would drain the tank and refill with premium. Try not to get any air into the system if you do this, makes life easier

MY KAWASAKI GPZ1000RX RIDES FINE UNTIL I'VE DONE +- 100KMH THEN SHE JURKS ALOT and also cannot go futher till 140kmh is it?

Could be a number of reasons from ignition through fueling or more. You will have to start diagnosing . Are you saying it jerks etc at near 100 kmh but then runs better at 140 kmh.

Your cylinder is worn. Its allowing oil past the ring. The oil is fouling the plug and the burning oil is causing the blue smoke. After 22 years the Kawi needs a freshened up top end.
